Ok, went riding today and i was racing kinda hard up this sandy, whooped out hill and when i was at 3/4 to WOT the bike would cut out, like it is starving for gas. any ideas on this problem? on the trails im fine, bike runs great. only did it a lot on the hill side. seems like the whoops is what was causing it. Its a 730 with FST stage 2 cams and the intake mod. stock carbs with 45 pilots and 245 mains. any help would be appreciated.
